English description（英文原文，共 1520 字符）
Product Name:Sodium L-Tartrate
English Name:Sodium L-Tartrate
CAS No.:868-18-8
Aliases:Disodium tartrate, Disodium L-(+)-tartrate, L-(+)-Tartaric acid disodium salt, Sodium tartrate dibasic
Molecular Formula:C4H4Na2O6·2H2O
Physical Properties:Colorless transparent prismatic crystals or white crystalline powder. Relative density 1.818 (25/4°C), melting point approximately 150°C. Soluble in 9 parts of cold water and 1.8 parts of boiling water; insoluble in ethanol and ether. Stable at room temperature and pressure, avoid contact with oxidizing agents; loses water of crystallization at 100°C to form the anhydrous salt, decomposes at 234°C in dry air. Usually exists as dihydrate, specific optical rotation approximately +29.5°. Keep container sealed and store in a cool, dry place.
Uses:Used as a chelating agent, acid adjustment agent, buffering agent, emulsifying salt, antioxidant and antioxidant synergist. In the food industry, it is used as a flavor-mellowing agent for soft drinks, sake, candies, jams, jellies and sparkling wine; when combined with tartaric acid, it softens the sour taste. It is also used in the processing of oils and fats, margarine, meat products and sausages. In biochemical research, it is used for vanadium determination and standardization of Karl Fischer reagent.
